ATTACHMENT FOR SEED-PLANTERS,

Application filed October 7, 1913. Serial No. 793,926. f

To all whom it may concern:

Be it known that I, ELI M. Lusx, a citizen of the United States, resident of Knox City, in the county of Knox and State of Texas, have made a certain new and useful Invention in Attachments for Seed-Planters; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 is a side view of the invention as applied with positions of parts as adjusted in dotted lines. Fig. 2 is a side view of the invention alone. Fig. 8 is a detail plan view of the rear plow beams. Fig. 4 is a section on the line 4-4 Fig. 3.

The invention has relation to seed planters and is designed for regulation of the depth of the small coverer plows in rear by the driver without dismounting from his seat. a

The invention consists in the novel construction and combinations of parts as hereinafter set forth.

In the accompanying drawings, illustrating the invention, the numeral 1 designates a seed planter of the type wherein the seed box is located in rear of the seat, said seat being placed well forward, overthe main axle. The usual seed box 2, seat 3, main plow 4, small coverer plows 5 and seed chute or drill 6 are shown. The coverer plows 5 are carried at the rear ends of rearward extending frame arms 7, pivoted forwardly at 8 to the main beam considerably in rear of the seat 3, and are adjusted by means of a lever 10, pivoted at its lower end at 11 close to the upper approximately horizontal portion of the main plow beam and having a connectin rod 12 for raising and lowering the arms 7 upon pivot 8. The adjustment is held by engagement of the pawl 13 of the lever with the teeth of the arc bar 14. Because of the position of the lever 10, as governed by the location of the seat 3, over the main plow 4, it is advisable to keep its lower pivotal end 11 well raised, close to the beam, well above the pivot 8, to avoid interference with the action of the plow. And in order to give a proper degree of movement to the coverer plows in their adjustment and to retain proper leverage by pivoting the rod 12 Specification of Letters Patent.

l 1 an'upwardly extending frame arm 9 is rigidly secured to the arm 7 near its free end, the connecting rod being attached to the upper end of this arm 9 and having an to the lever 10' at a point close to the pivot The 1 bolt 12 having engagement with any one I of a series of perforations 12 of said connecting rod, said rod being thus capable of being secured in the proper angular relation to lever 15, previously stated. It is designed to provide an attachment having the advantages stated and which may be readily connected both to the pivotal arms 7,

carrying the coverer plows, and to the plow beam. To this end the rackbar 14 is provided with forward and rearward extending brace arms 14, adapted for connection at their free ends with the plow beam upon opposite sides of the rack, to hold it securely in place close to the upper approximately horizontal portion of the beam, and the transverse bar 9 is provided with down turned ends 9* to embrace the arms 7, and perforated for the transverse bolt 9 the upward extending arm 9 being rigidly secured to one of said downturned ends by pin 9 In this way, in making the COI1I16C- tion, it is only necessary to bolt the rack bar 14 in place and to secure the transverse bar 9 to the arms 7. I

When the front plow is adjusted for depth by operation of the lever .15 to turn the crank axle 16 in the usual way, the rear plows will be simultaneously adjusted for depth, the special adjustment of my invention allowing for this.

By the use of my invention, it is not necessary for the team to be stopped when the special or independent adjustment of the rear plows is to be made, time being saved being accomplished more satisfactorily.

The lever 10 is smaller than the main lever 15, and located in rear of the same behind approximately horizontal portion of the plow beam, a lever pivoted to ,said rack bar and having a pawl connection therewith, a transverse bar having detachable connection with said pivotal arms and provided with an upward extending arm rigid therewith and a connecting rod between said lever and the upper end of said upward extending arm. a

2. The combination with a seed planter;

having a seed box in rear of its seat and rearward extending plvotal arms carrying .coverer plows, of an attachment comprising a rack bar secured 1n place close to the upper approximately horizontal portion of the plow beam, a lever pivoted to said rack bar and having a pawl connectiontherewith, a

transverse bar having detachable connection with said pivotal arms and provided with an upward extending arm rigid therewith, and

copies of this patent may be obtained for a rod having connection with said lever near the pivot thereof and adjustable connection with the upper end of said upward extendmg arm. 7

3. An attachment for seed planters having a seed box in rear of the seat and rearward extending pivotal arms carrying coverer plows, comprising a rack bar having forward and rearward extending brace arms for connection with the upper horizontal portion of a plow beam, close thereto, a lever pivoted to said rack bar and having a pawl connection therewith to fix the adjustment, a transverse bar having downturned ends to embrace said pivotal arms, an upward extending arm rigidly secured to one of said ends, and a transverse bolt engaging perforations of said ends and of said pivotal arms, and a connecting rod between said lever and the upper end of said upward extending arm.

In testimony whereof I affix my signature, in presence of two witnesses.
